Eric Drexler

Kim Eric Drexler (born April 25, 1955) is an American engineer best known for introducing molecular nanotechnology (MNT), and his studies of its potential from the 1970s and 1980s.[1] His 1991 doctoral thesis at Massachusetts Institute of Technology (MIT) was revised and published as the book Nanosystems: Molecular Machinery Manufacturing and Computation (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. He has been called the "godfather of nanotechnology". https://en.wikipedia.org/wiki/K._Eric_Drexler

• The term "nano-technology" had been coined by the Tokyo University of Science professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and Drexler unknowingly used a related term in his 1986 book Engines of Creation: The Coming Era of Nanotechnology to describe what later became known as molecular nanotechnology (MNT). In that book, he proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity. He also first published the term "gray goo" to describe what might happen if a hypothetical self-replicating molecular assembler went out of control. He has subsequently tried to clarify his concerns about out-of-control self-replicators, and make the case that molecular manufacturing does not require such devices.
